Voyager Golden Record
Voyager Golden Records er to fonografiske plader der var fastgjort på de to Voyagerrumsonder, der blev opsendt i 1977.[1] Pladerne indeholder lyde og billeder, der er udvalgt til at vise diversiteten af livet og kultur på Jorden, og de er tilsigtet intelligent udenjordiskesformer, eller fremtidige mennesker, der måtte finde dem. Pladerne bliver betragtet som en slags tidskapsel.
Selvom ingen af Voyager-rumfartøjerne bevæger sig mod nogen særlig stjerne, så vil Voyager 1 passere i en afstand af 1,6 lysår af stjernen Gliese 445, der befinder sig i stjernebilledet Giraffen, om omkring 40.000 år.[2]
Carl Sagan bemærkede at "Rumfartøjet bliver fundet og pladen bliver spillet udelukkende der findes avancerede rumfarende civilisationer i det ydre rum, men opsendelsen af denne "flaske" i det kosmiske "hav" fortæller noget meget håbefuldt om denne planet." [3]

Voyager Golden Record
This gold aluminium cover was designed to protect the Voyager 1 and 2 "Sounds of Earth" gold-plated records from micrometeorite bombardment, but also serves a double purpose in providing the finder a key to playing the record.
The explanatory diagram appears on both the inner and outer surfaces of the cover, as the outer diagram will be eroded in time. Flying aboard Voyagers 1 and 2 are identical "golden" records, carrying the story of Earth far into deep space. The 12 inch gold-plated copper discs contain greetings in 60 languages, samples of music from different cultures and eras, and natural and man-made sounds from Earth. They also contain electronic information that an advanced technological civilization could convert into diagrams and photographs. Currently, both Voyager probes are sailing adrift in the black sea of interplanetary space, flying towards the outmost border of our solar system.A drawing of NASA's Space Shuttle Challenger.
